Tree pollen carries SARS-CoV-2 particles farther, facilitates virus spread
Most models explaining how viruses are transmitted focus on viral particles escaping one person to infect a nearby person. A study on the role of microscopic particles in how viruses are transmitted suggests pollen is nothing to sneeze at......»»
Seeing a black hole"s jet in a new light: A look at high-energy particles being blasted across space
Research led by the University of Michigan has pored over more than two decades' worth of data from NASA's Chandra X-Ray Observatory to show there's new knotty science to discover around black holes......»»
The Colors of Fall Leaves Are Shaped by Climate Change and Tree Health
A tree’s fall palette offers a glimpse at its health and the weather it has experienced in a given year.....»»
The Surprising Story of How Peaches Became an Icon of the U.S. Southeast
The Spanish brought peaches to the U.S., but Indigenous peoples spread the fruit across the eastern half of the U.S......»»
An Enormous Meteorite, Bird Flu in Washington State and a Troubling Scurvy Case Study
We cover a 3.26-billion-year-old meteorite impact, the spread of bird flu and a scurvy case study that serves as a cautionary tale in this week’s news roundup......»»
The Secret Electrostatic World of Insects
Invisibly to us, insects and other tiny creatures use static electricity to travel, avoid predators, collect pollen, and more. New experiments explore how evolution may have influenced this phenomenon......»»
For heating plasma in fusion devices, researchers unravel how electrons respond to neutral beam injection
Heating a plasma for fusion research requires megawatts of power. One approach that research tokamaks use to achieve the necessary power input is neutral beam injection (NBI). With NBI, fast neutral particles are generated in a device called a beam s.....»»
Bacterial pathogen must balance between colonizing airways and developing antibiotic tolerance, study reveals
Imagine trying to settle into a new home while constantly being attacked. That's what the bacterium Pseudomonas aeruginosa faces when it infects the lungs, and it can't both spread and protect itself from antibiotics at the same time......»»
Search results for dark photon leptonic decays manage to exclude new regions
Dark photons are hypothetical particles that resemble light particles (i.e., photons), but interact weakly with normal matter, which would make them impossible or very difficult to detect using conventional experimental methods. These particles are d.....»»
Synthesis method improves catalytic activity by controlling the surface structure of metal particles
Fine-tuning the reactions that produce hydrogen (H2) for use as a clean fuel is an important endeavor to fight against climate change. Researchers at Tohoku University and the Tokyo University of Science have succeeded in improving the catalytic acti.....»»
Bird flu hit a dead end in Missouri, but it’s running rampant in California
No new cases in Missouri, but plenty in California and Washington. As H5N1 bird flu continues to spread wildly among California dairy herds and farmworkers, federal health officia.....»»
Warming lakes and rivers may spread fish pathogens
Michigan's rivers and lakes were once cold enough that fish were protected from some infection-causing parasites. As the Great Lakes ecosystem warms, a Michigan State University researcher is investigating new pathogens that may become relevant to th.....»»
Tiny airborne particles within air pollution could be a silent killer
Long-term high ultrafine particle concentrations in New York state neighborhoods are linked to higher numbers of deaths. That is the key finding of our new research, published in the Journal of Hazardous Materials......»»
Biologists discover a new fossil species of prehistoric fish
What do the ginkgo (a tree), the nautilus (a mollusk) and the coelacanth (a fish) all have in common?.....»»
When ribosomes go rogue
Unusual variations in the cellular protein factory can skew development, help cancer spread, and more. But ribosome variety may also play biological roles, scientists say. In the.....»»
High-resolution, nanoscale imaging method could accelerate the discovery of more durable materials
Take a photo with your phone and you might see wonderful details—leaves on a tree, strands of hair blowing in the wind. The width of that strand of hair is 100,000 nanometers wide. The best traditional laboratory microscope that uses light may capt.....»»

Researcher finds special proteins are key when antibiotic resistance spreads
Antibiotic resistance is a growing public health problem globally. The problem is exacerbated by the fact that some bacteria that have become resistant to antibiotics have the ability to spread that resistance to other bacteria via secretion systems......»»
Invasive tree logs show promise for mushroom production
An article in the latest issue of Invasive Plant Science and Management provides new insights on the varying potential for using invasive tree logs to grow edible, marketable mushrooms......»»
Structural biology analysis of a Pseudomonas bacterial virus reveals a genome ejection motor
The viruses that infect bacteria are the most abundant biological entities on the planet. For example, a recent simple study of 92 showerheads and 36 toothbrushes from American bathrooms found more than 600 types of bacterial viruses, commonly called.....»»
"Nano-weapon" discovery boosts fight against antibiotic-resistant hospital superbugs
Researchers have discovered how a bacteria found in hospitals uses "nano-weapons" to enable their spread, unlocking new clues in the fight against antibiotic-resistant superbugs......»»
